ICL implantation is now a relatively mature method of myopia correction, but it may cause problems such as iridocyclitis, glaucoma, and overcorrection and undercorrection. ICL implantation requires placing a lens in the anterior chamber through an incision at the corneal edge to correct myopia. However, since it is a traumatic surgery and will affect the iris and the depth of the anterior chamber to a certain extent, iridocyclitis, endophthalmitis, glaucoma and other hazards may occur in the event of imperfect preoperative examination and insufficient surgical experience. And ICL myopia surgery in the calculation of the lens degree is too high or too low, there may be overcorrection or undercorrection and so on, appear after the operation of the naked eye visual acuity can not meet the expectations; also may be due to the postoperative environment or improper care and other factors, so as to appear in the cornea and conjunctiva and other infections. It is recommended to be cautious when choosing ICL myopia surgery, try to choose hospitals and doctors with rich surgical experience and guaranteed postoperative results, and consult a doctor in time to deal with any abnormality.
